PERFORMANCE OF WHEAT CROP UNDER DIFFERENT TREE CROP COMBINATION OF A LAND USE SYSTEMYogesh Kumar, Anita Thakur and Tarun Kumar Thakur
Agri-horti-silviculture system of agroforestry are very suitable to marginal or small farmers. The basic needs of food, fodder, fuel and timber for farmers in addition to its economic benefits can be easily fulfilled with this combination of cropping system. Among several combinations one of the suitable systems in hilly area with wheat, aonla and sissoo. A study was carried out to evaluate the performance of wheat as under storey crop with different proportion of tree combinations. Five treatments viz. 100% Emblica officinalis, 75% Emblica officinalis + 25% Dalbergia sissoo, 50% Emblica officinalis + 50% Dalbergia sissoo, 25% Emblica officinalis + 75% Dalbergia sissoo and 100% Dalbergia sissoo were selected for the study. Wheat production trend was evaluated continuously for two years from 2017-18 to 2018-19. One-year old trees were planted with desired combinations in all the treatments. Wheat variety JW-3173 was grown in all two years. Significantly highest grain yield was recorded in agroforestry (AF) with 100% Aonla (1758.25 and 1519.5 kg/ha/yr during 2017-18 and 2018-19 respectively) than all other treatments. In case of straw yield and harvest index same trend was observed during both the years. The reduction of yield was observed due to increase of canopy of tree during subsequent years.
